<gamiee> swiftgeek: edid file handle is here, but empty.
<swiftgeek> so no edid
<swiftgeek> check whether shield is continuous, and then other relevant gnd/hotplug signals
<swiftgeek> and 5V supply
<gamiee> swiftgeek: fun fact, after testing older Armbian build, the display works
<jernej> gamiee: I guess that means BSP kernel?
<gamiee> jernej: no, all mainline
<gamiee> just older version
<jernej> ok, because BSP kernel doesn't use EDID
<gamiee> The thing is, it seems that even u-boot can't get display working
<gamiee> but everything works on older Armbian build.
<gamiee> https://armbian.hosthatch.com/archive/pine64so/archive/Armbian_22.08.7_Pine64so_bullseye_current_5.15.74.img.xz This is kernel 5.15.74, CLI version and it works. Also I know that some newer Armbian works, but only CLI versions. None of desktop version works.
<gamiee> Even my build of Linux 6.0.0 and one of latest u-boots doesn't work
<jernej> note that mainline dw-hdmi driver has often fixes around plug detection
<jernej> but that still doesn't explain u-boot
<jernej> except if U-Boot messes up kernel, which happens for me on OrangePi PC2
<jernej> can you try disabling HDMI in U-Boot?
<gamiee> jernej: sadly, it is hard to test this, since this is happening to someone else, I can't reproduce it by myself.
<gamiee> But it seems that the HDMI cable is the issue
<gamiee> Yup, cable
<gamiee> But it is still weird that on older Armbian it works fine :D
<swiftgeek> welp some cables aren't compliant and have bad wiring
<swiftgeek> you can dump edid with other cable and pass that to kernel

<gamiee> Yeah, but why old Armbian works...
<swiftgeek> does it get edid?
<gamiee> the output works, so I guess, but will ask for check
<swiftgeek> also edid of that particular screen not something simulated

<gamiee> Also, note that for some reason, card1 is DE2, card0 is LIMA
ftg has joined #linux-sunxi
<gamiee> swiftgeek & jernej: on that older Armbian build, edid returns nothing, but FB and console works. So it seems that EDID is not working
